Android Build an Interactive Story App (Retired) Finishing the User Interface Using a Model in the Controller

I don't understand why this challenge compiler won't accept my code to covert an int to a String.

I need to convert an int to a string and set it to an EditText in this challenge for building an Interactive Story.

I am stuck. I researched info on StackOverFlow, and Oracle, but I just can't seem to understand what it is I am missing. I understand that this challenge compiler is looking for something specific, but I just don't know what specifically it's looking for.

LandingActivity.java 
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class LandingActivity extends Activity {

    public Button mThrustButton;
    public TextView mTypeLabel;
    public EditText mPassengersField;

    public Spaceship mSpaceship;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);

        mThrustButton = (Button)findViewById(R.id.thrustButton);
        mTypeLabel = (TextView)findViewById(R.id.typeTextView);
        mPassengersField = (EditText)findViewById(R.id.passengersEditText);

        // Add your code here!
      mSpaceship = new Spaceship("FIREFLY");
      mTypeLabel.setText(mSpaceship.getType());
      String intAsString = String.valueOf(0);
      mPassengersField.setText(mSpaceship.getNumPassengers(intAsString));
    }
}
Spaceship.java 
public class Spaceship {
    private String mType;
    private int mNumPassengers = 0;

    public String getType() {
      return mType;
    }

    public void setType(String type) {
      mType = type;
    }

    public int getNumPassengers() {
      return mNumPassengers;
    }

    public void setNumPassengers(int numPassengers) {
      mNumPassengers = numPassengers;
    }

    public Spaceship() {
      mType = "SHUTTLE";
    }

    public Spaceship(String type) {
      mType = type;
    }
}

To convert the number of passengers to a String, you can convert the return value of getNumPassengers via the valueOf method on the String class:

mPassengersField.setText(String.valueOf(mSpaceship.getNumPassengers()));

//Answer is:
        mPassengersField.setText(mSpaceship.getNumPassengers() + "");
//You were trying to parse a string into the function that doesn't accept any arguments.
//Simply doing + "" will convert it to string.

Wow, thank you both. I am assuming they both will work just fine, because i did research on String.valueOf() and wasn't aware to think to put the mSpaceship object into the parameters of String.valueOf.

Thank you!
